+<p>
+ONELAB is an open-source, lightweight interface to finite element software. It
+is completely free: the default ONELAB software bundle contains the mesh
+generator <a href="http://gmsh.info">Gmsh</a> and the finite element solver
+<a href="http://getdp.info">GetDP</a>. Many other codes (free or not) can be
+easily interfaced as well.
+</p>
+
+<h2>Give it a try!</h2>
+
+<ol>
+  <li>Download the ONELAB software bundle:
+  <ul>
+    <li>Desktop version for <a href="http://onelab.info/files/onelab-Windows64.zip">Windows</a>
+      (<a href="http://onelab.info/files/onelab-Windows32.zip">32 bit</a>),
+      <a href="http://onelab.info/files/onelab-Linux64.zip">Linux</a> and
+      <a href="http://onelab.info/files/onelab-MacOSX.dmg">MacOS</a>
+    <li>Mobile version for <a href="https://play.google.com/store/apps/details?id=org.geuz.onelab">Android</a> and
+      <a href="https://itunes.apple.com/us/app/onelab/id845930897">iOS</a>
+    <li><a href="http://onelab.info/files/onelab-source.zip">Source code</a>
+  </ul>
+  <li>Launch the app <img src="http://geuz.org/gmsh/gallery/icon.png" height=20px>
+  <li>Open a model:
+  <ul>
+    <li>Desktop version: go to the <code>File/Open</code> menu and select a
+    GetDP <code>.pro</code> file,
+    e.g. <code>models/magnetometer/magnetometer.pro</code>
+    <li>Mobile version: select one of the preloaded models
+  </ul>
+  <li>Press <code>Run</code>.
+  <li>... then explore <a href="http://gitlab.onelab.info/doc/models/wikis">other models</a>
+</ol>
+
+<h2>Use existing clients</h2>
+
+<p>
+  <em>Native</em> clients directly embed the ONELAB library:
+</p>
+<ol>
+  <li><a href="http://getdp.info">GetDP</a>: a finite element solver for
+  electromagnetism, heat transfer, acoustics and generic PDEs
+  <li><a href="http://gmsh.info">Gmsh</a>: a mesh generator and post-processor
+  (Gmsh also plays the role of ONELAB server)
+  <li>Onelab/Mobile: GetDP and Gmsh
+  on <a href="https://itunes.apple.com/us/app/onelab/id845930897">iPhone, iPad</a>
+  and <a href="https://play.google.com/store/apps/details?id=org.geuz.onelab">Android</a>
+  devices
+</ol>
+
+<p>
+Other clients (<em>non-native</em>) are interfaced with ONELAB by a system of
+input file pre-processing. The different steps of a simulation (meshing,
+solving, post-processing) are controlled by a python script. See worked-out
+examples with:
+</p>
+<ol>
+  <li><a href="http://gitlab.onelab.info/doc/models/wikis/Elmer">Elmer</a>: a
+  finite element solver for multi-physic problems developed by CSC
+  <li><a href="http://gitlab.onelab.info/doc/models/wikis/OpenFOAM">OpenFOAM</a>:
+  an open source CFD software package developed by OpenCFD
+</ol>
+<p>
+  Any software driven by input data files (e.g. Code_Aster, Abaqus, CalculiX,
+  FreeFem, Gnuplot, ...) can be readily interfaced in the same way.
+</p>
+<p>
+  Here are
+  some <a href="http://gitlab.onelab.info/doc/models/wikis/Hints">useful hints
+  to efficiently use the ONELAB graphical user interface</a>.
+</p>
+
+<h2>Develop your own client</h2>
+
+<p>
+Implement your own native ONELAB clients:
+</p>
+<ol>
+  <li><a href="http://gitlab.onelab.info/doc/models/wikis/Python">With
+      Python</a>: any Python code can become a native ONELAB client
+  <li><a href="http://gitlab.onelab.info/doc/models/wikis/C++">With C++</a>: how
+  to create a native C++ ONELAB client
+</ol>
+
+<h2>Technical information</h2>
+
+<p>
+The ONELAB interface allows calling sequences of independent clients (e.g. mesh
+generators, finite element solvers and other related tools) and have them share
+parameters and modeling information. It is based on an abstraction of the
+interface to finite element solvers and related tools: for geometry modeling and
+meshing, for the definition of physical properties, constraints and other solver
+parameters, and for post-processing.
+</p>
+<p>
+The implementation is based on a client-server model, with a server-side
+database and (optional) graphical front-end, and local or remote clients
+communicating in-memory or through TCP/IP sockets. Contrary to most available
+solver interfaces, the ONELAB server has no <em>a priori</em> knowledge about
+any specifics (input file format, syntax, ...) of the clients. In practice, this
+is made possible by having any simulation preceded by an analysis phase, during
+which the clients are asked to upload their parameter set to the server.
+</p>
+<p>
+Native ONELAB clients can be written in C++ or Python, and embed the ONELAB
+library. For native clients the specification of which data to share is
+completely dynamic. For non-native clients, the ONELAB server acts as a
+pre-processor of their input files, which should be instrumented to specify the
+information to be shared. In all cases the issues of completeness and
+consistency of the parameter sets are completely dealt with on the client side:
+the role of ONELAB is limited to data centralization, modification and
+re-dispatching.
